Abstract

We investigated the photoluminescence (PL), radioluminescence (RL) and thermally-stimulated luminescence (TSL) properties of Pr:CaSiO3 crystals grown by the floating zone method. In both the PL and RL spectra, a broad emission band are observed around 300 nm due to the 5d-4f transitions of Pr3+, whose decay time constants are 16–20 ns and 140–260 ns. In TSL, multiple glow peaks are observed over 50–250 °C, and the response intensity increases linearly proportional to the X-ray dose.
